What to build

Implement dot kde apply for schema-backed settings: read every entry in the manifest and write its declared value onto the live system via kwriteconfig6. Re-running it against an already-applied system must be a no-op with no unintended side effects — this is the idempotence the feature depends on for safe re-runs after a KDE update or on a freshly built machine. Add dot kde apply help, following the project's check-for-help-before-argparse convention.

Add a README row for dot kde apply.

Acceptance criteria

• dot kde apply pushes every manifest entry's declared value onto the live system via kwriteconfig6
• Re-running dot kde apply against a system already matching the manifest changes nothing (idempotent)
• dot kde apply help prints usage without writing anything
• Tests run against a scratch $HOME, exercising apply over a manifest with schema-backed entries, verifying resulting rc-file contents and idempotence on a second run
• README has a row for dot kde apply
